Considering purchasing a hitch for my wife's 2015 Jeep Grand Cherokee. She doesn't have the diesel, just the V6. I think towing is close to 6k but not sure I want to drop $220 if it's going to tow like crap. I've got a single axle trailer under my X2 so I won't be close to that 6,000lb capacity.

Just picked up a Mercedes GL350 Desiel over the weekend. Drove it home 150 miles at 75 to 85 mph and got 25.5 mpg. I LOVE IT. Can't wait to put the boat behind it this weekend. IMHO, it's the perfect toy hauler.
